The device may apply an offset value to the first signal quality value to form a modified signal quality value, may compare the combined signal quality value and the modified signal quality value, and may selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A device, comprising: one or more processors to: determine a first signal quality value associated with a wireless signal received by a first antenna of the device; determine a second signal quality value associated with a wireless signal received by a second antenna of the device; determine a combined signal quality value based on the first signal quality value and the second signal quality value; apply an offset value to the first signal quality value to form a modified signal quality value; compare the combined signal quality value and the modified signal quality value; and selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value.
A device monitors signal quality from two antennas. It determines a first signal quality value from the first antenna, and a second signal quality value from the second antenna. It combines these two values into a single, combined signal quality value. To compensate for antenna imbalance, an offset is applied to the first signal quality value, creating a modified signal quality value. The device then compares the combined signal quality value with the modified signal quality value. Based on this comparison, the device selectively reports either the combined or the modified signal quality, enabling optimized signal reporting.
2. The device of claim 1 , where the first signal quality value includes a first reference signal received power (RSRP) value; and where the second signal quality value includes a second RSRP value.
The signal quality monitoring device described previously uses Reference Signal Received Power (RSRP) values to measure signal quality. Specifically, the "first signal quality value associated with a wireless signal received by a first antenna of the device" is a first RSRP value, and the "second signal quality value associated with a wireless signal received by a second antenna of the device" is a second RSRP value.
3. The device of claim 1 , where the one or more processors, when comparing the combined signal quality value and the modified signal quality value, are to: determine whether the modified signal quality value is less than or equal to the combined signal quality value.
When the signal quality monitoring device compares the combined signal quality value and the modified signal quality value (as described in the first signal quality monitoring device), it determines if the modified signal quality value is less than or equal to the combined signal quality value. This comparison is used to decide whether to report the modified or combined value.
4. The device of claim 1 , where the first antenna is used to transmit and receive wireless signals; and where the second antenna is used to receive wireless signals.
The signal quality monitoring device described earlier has a first antenna that is used for both transmitting and receiving wireless signals. The second antenna is used only to receive wireless signals. The device "determines a first signal quality value associated with a wireless signal received by a first antenna of the device; determine a second signal quality value associated with a wireless signal received by a second antenna of the device; determine a combined signal quality value based on the first signal quality value and the second signal quality value; apply an offset value to the first signal quality value to form a modified signal quality value; compare the combined signal quality value and the modified signal quality value; and selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value."
5. The device of claim 1 , where the one or more processors are further to: determine that a difference between the first signal quality value and the second signal quality value satisfies a threshold; and where the one or more processors, when applying the offset value to the first signal quality value, are to: apply the offset value to the first signal quality value based on determining that the difference between the first signal quality value and the second signal quality value satisfies the threshold.
In addition to the features of the base signal quality monitoring device, the device also determines if the difference between the first and second signal quality values exceeds a certain threshold. Only when this threshold is met will the device apply the offset to the first signal quality value to produce the modified value, ensuring the offset is only used when antenna imbalance is significant and relevant "the device to determine a first signal quality value associated with a wireless signal received by a first antenna of the device; determine a second signal quality value associated with a wireless signal received by a second antenna of the device; determine a combined signal quality value based on the first signal quality value and the second signal quality value; apply an offset value to the first signal quality value to form a modified signal quality value; compare the combined signal quality value and the modified signal quality value; and selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value."
6. The device of claim 1 , where the modified signal quality value is greater than or equal to the first signal quality value.
The modified signal quality value generated by the signal quality monitoring device (where "the device to determine a first signal quality value associated with a wireless signal received by a first antenna of the device; determine a second signal quality value associated with a wireless signal received by a second antenna of the device; determine a combined signal quality value based on the first signal quality value and the second signal quality value; apply an offset value to the first signal quality value to form a modified signal quality value; compare the combined signal quality value and the modified signal quality value; and selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value") is always greater than or equal to the original first signal quality value.
7. The device of claim 1 , where the one or more processors are further to: receive the offset value from a base station; and where the one or more processors, when applying the offset value to the first signal quality value, are to: apply the offset value to the first signal quality value based on receiving the offset value from the base station.
The signal quality monitoring device ( "the device to determine a first signal quality value associated with a wireless signal received by a first antenna of the device; determine a second signal quality value associated with a wireless signal received by a second antenna of the device; determine a combined signal quality value based on the first signal quality value and the second signal quality value; apply an offset value to the first signal quality value to form a modified signal quality value; compare the combined signal quality value and the modified signal quality value; and selectively report the modified signal quality value or the combined signal quality value based on comparing the combined signal quality value and the modified signal quality value") receives the offset value from a base station.

The computer-readable medium, as described previously, stores instructions that cause the device to determine if the difference between the first and second signal quality values meets a threshold.

A method involves a device measuring a first signal quality parameter to determine a first signal quality value from a first antenna, and measuring a second signal quality parameter to determine a second signal quality value from a second antenna. The device combines these values into a combined signal quality value. An offset is applied to the first signal quality value to generate a modified signal quality value.

In addition to the core method previously described, the device determines if the combined signal quality value is less than or equal to the modified signal quality value. If this condition is true, the combined signal quality value is provided for the network procedure (instead of the modified value, as described in the device measuring a first signal quality parameter to determine a first signal quality value from a first antenna, and measuring a second signal quality parameter to determine a second signal quality value from a second antenna. The device combines these values into a combined signal quality value. An offset is applied to the first signal quality value to generate a modified signal quality value.

In addition to the core method, the device determines if the modified signal quality value is less than or equal to the combined signal quality value. If this condition is met, the *modified* signal quality value is provided for the network procedure, rather than the combined value. This method starts when "a device measures a first signal quality parameter to determine a first signal quality value from a first antenna, and measures a second signal quality parameter to determine a second signal quality value from a second antenna; the device combines these values into a combined signal quality value; an offset is applied to the first signal quality value to generate a modified signal quality value; then the device compares the combined and modified values, and provides either the combined or modified value for use in a network procedure, based on this comparison".
